Are pi bonds are only delocalized bonds?
No, in aromatic compounds and some aliphatic compounds have deloclized pi bonds but in most of the alkenes and alkynes there are localized pi bonds.
What are the two methods of preparing alkynes?
There are more than two methods to prepare alkynes, but for example you can do a double elimination reaction by way of E2 (double dehydrohalogenation), a more direct way and using one reaction only you can use KOH @ 200 degrees Celsius for a central alkyne, or NaNH2 @ 150 degrees Celsius for a terminal alkyne.
What is the definition of hydocarbon?
In organic chemistry, a hydrocarbon is a compound consisting of only carbon and hydrogen atoms. There are different types of hydrocarbons, such as saturated hydrocarbons, which include alkanes (e.g.- methane), unsaturated hydrocarbons, which include alkenes and alkynes (e.g.- ethylene and ethyne), cycloalkanes (e.g. - cyclopropane), and arenes, also known as aromatic hydrocarbons (e.g. - benzene).
What special form of diffusion tgat applies only to water?
Osmosis is the form the applies only to water. This is only in high waters.
How many types of natural atoms are there?
There are 90 naturally occurring types of atoms, or elements.
What Compounds that contain only carbon and hydrogen are .?
They can be alkanes,alkenes and alkynes. They are commonly called hydrocarbons.
What are the types of bond present in alkanes alkenes and alkynes?
Alkanes have only single carbon-carbon bond.Alkenes have min. a double carbon-carbon bond.Alkynes have min. a triple carbon-carbon bond.
Do alkynes only have triple bonds?
AN alkyne is a functional groups that is a triple bond between two carbon atoms.
What are compounds that contain only carbon and hydrogen atoms?
Many compounds are composed of only carbon and hydrogen. These are the core of the group called hydrocarbons. They include compounds such as:methaneoctanepentanebenzenetoluenexylene
What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
What is a compound that contains only elements carbon and hydrogen?
These compounds are generally known as hydrocarbons. Some of the hydrocarbon groups include alkanes, alkenes and alkynes.
How many types of birth certificates does Hawaii issue?
Up until June 2009 it issued 2 types, a "short form" or "abstract" and a "long form" which was a photocopy of the record on file. Now it only issues the short form.

no.. both are
